Wright, General Manager RECOMMENDATION: Adopt Resolution 2023-12 accepting the Roundhill Tank Rehabilitation project as complete and authorize the filing of the Notice of Completion. BACKGROUND: The Roundhill Tank is a 300,000-gallon welded steel tank located in Tahoe Donner. On May 04, 2022, the Board awarded the rehabilitation contract for the Roundhill Tank project to the Resource Development Company (RDC) of Sparks, Nevada. The project involved rehabilitating the Roundhill tank by performing the following objectives: • Identify and repair failing welds • Remove and replace tank roof access hatch and handrail • Install "Candy Cane" style tank vents • Replace existing tank side vent cover plates • Provide sample tap assembly with lock Box • Replace interior and exterior coating system The bid price was $585,160. The Board also established a ten percent change order allowance of $58,540, for a total authorization not to exceed $643,700. During the initial scope of the work, additional degradation of the tank wall metal and welds were discovered. Subsequently, RDC proposed a second, more comprehensive change order for the additional work that was approved by the Board during the August Board Meeting. The Board authorized change order allowance was $62,400 for a new not to exceed the amount of $706,100. ANALYSIS AND BODY: Page 1 of 3 Page 38 of 85 Tank rehabilitation work began during the summer of 2022 and was put back in service on July 12, 2023. With the early onset of winter and additional work done on this tank, the project had to be extended through the winter of 2023 due to the temperatures being too low for the application of the interior and exterior coating systems. During the course of the project, two change order requests were submitted and reviewed by staff. After review and discussion, the District and RDC agreed on a total of $72,384.00 for the change orders. The items were: • Additional welding was requested for a sum of $9,984 • After the final removal of the interior and exterior coating systems, pitting and corrosion of the parent steel near the welds was more significant than anticipated. • After discussions with RDC and Carollo Engineers, it was agreed that installing cover plates over the areas with significant pitting and corrosion would be the most cost-effective approach to extend the useful life of the tank. • This band would be 10" wide and would cover the entire perimeter of the tank (both inside and outside) at the second horizontal seam and the adjoining vertical welds. • In other areas of the tank where pitting has occurred, 4" diameter steel plates were installed on the interior only. RDC provided a cost proposal of$62,400 for the additional labor and materials associated with this additional work. This amount exceeded the original change order allowance and was taken back to the Board of Directors' regular meeting for approval on 08/03/2022. In August, District staff performed a final walkthrough of the project. The work performed is complete and should be accepted by the District. Attached is a draft resolution (Attachment 1) accepting the project and directing that a Notice of Completion be filed. GOALS AND OBJECTIVES: District Code 1 .05.020 Objectives: 3.
